What this Trial Is About
The benefit-risk profile of thrombolysis for acute ischemic strokes beyond 24 hours has never been investigated. We initiated a multicenter, prospective, randomized, open label, blinded-endpoint (PROBE) controlled trial to assess the safety and efficacy of tenecteplase (0.25mg/kg, max 25mg) versus standard medical treatment in acute ischemic stroke due to intracranial vessel occlusion between 24-72 hours of symptom onset (including wake-up stroke and unwitnessed stroke).

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Age 18 years or older
- Stroke symptom onset between 24 to 72 hours before enrollment, including wake-up and unwitnessed strokes
- Pre-stroke modified Rankin Scale (mRS) score of 1 or less
- Baseline NIH Stroke Scale (NIHSS) score between 6 and 25, or score of 4 or 5 with a disabling deficit such as hemianopia, aphasia, or loss of hand function
- Confirmed occlusion of middle cerebral artery (M1-M4), anterior cerebral artery, posterior cerebral artery, or basilar artery by CTA/MRA causing stroke symptoms
- Target mismatch profile on perfusion imaging (ischemic core volume less than 70 mL, mismatch ratio greater than 1.2, and mismatch volume greater than 10 mL)
- Written informed consent from patient or legally authorized representative
You will not qualify if you...
- Significant low-density lesion on CT scan
- Allergy to tenecteplase
- Rapidly improving stroke symptoms
- NIHSS consciousness score 1a greater than 2, epileptic seizure, Todd's palsy, or inability/unwillingness to cooperate
- Persistently high blood pressure (systolic ≥185 mmHg or diastolic ≥110 mmHg) despite treatment
- Blood glucose less than 2.8 or greater than 22.2 mmol/L
- Active internal bleeding or high bleeding risk from recent surgery, trauma, hemorrhage, or arterial puncture
- Known blood clotting problems or recent use of certain blood thinners without reversal
- Platelet count below 100,000/mm3 or known platelet function defects
- Recent ischemic stroke, heart attack, brain injury, brain surgery, or known brain abnormalities within 3 months
- Terminal illness with life expectancy under 1 year
- Unable to undergo perfusion imaging tests
- Large brain area affected on CT scan (more than one-third of middle cerebral artery territory or low pc-ASPECTS score)
- Acute or past brain hemorrhage on imaging
- Multiple artery occlusions
- Pregnancy, breastfeeding, or refusal to use contraception
- Unlikely to follow study protocol or attend follow-ups
- Any condition judged by investigator to pose hazards or affect participation
- Participation in other interventional clinical trials within past 3 months
